Products classified under HTS 2620.21.00.50
Leaded Gasoline Sludge with Gold Impurities
Residue from leaded gasoline production containing mainly lead along with gold content from catalytic processes or impurities. Classified under HTS 2620.21.0050 due to its primary lead composition and gold metal content, fitting Chapter 26 for slag, ash, and residues used in metal extraction. Excludes iron/steel manufacturing residues per chapter notes.
Leaded Anti-Knock Compound Sludge with Gold Residue
Sludge byproduct from leaded anti-knock compound manufacturing, primarily lead-based with trace gold from alloyed components. Falls under HTS 2620.21.0050 for leaded sludges containing gold, used in industry for metal recovery. Meets chapter note (b) for arsenic/metal-containing residues for extraction.
Refinery Leaded Slag with Gold and Arsenic
Slag from petroleum refinery leaded fuel processing, mainly lead with gold and arsenic compounds for potential extraction. HTS 2620.21.0050 applies to such leaded sludges/slags with gold content, per chapter notes for industrial metal recovery uses.
Aviation Leaded Fuel Sludge with Gold Traces
Sludge from leaded aviation gasoline (avgas) production or cleanup, predominantly lead with incidental gold from refining. Classified in 2620.21.0050 for leaded gasoline sludges reporting gold content, used for metal reclamation.
TEL Manufacturing Leaded Residue with Gold
Residue from tetraethyllead (TEL) anti-knock compound production, lead-rich sludge with gold impurities from raw materials. HTS 2620.21.0050 covers such leaded anti-knock sludges with gold, for industrial metal compound manufacture.
Leaded Fuel Tank Bottom Sludge Gold Bearing
Settled sludge from storage tanks holding leaded fuels, mainly lead with gold content from accumulated impurities. Fits 2620.21.0050 for leaded gasoline sludges used in industry for metal extraction.
